Our phone number is listed as a contact number for 17 places that are not us. How do we change this? Do we have to contact each business and ask them to update the information?

Hello,

Where are you seeing your phone number on these 17 locations?

If it is on google search results you can request to change it if it is inaccurate.

If it is on their webpages you will have to contact them, an easy way to do this would be to get their email addresses and send an email requesting they remove your phone number from their information list.

Hope this helps,

JC
